SPECIFICATION forming part Of Letters Patent No. 668,116, dated February12, 1901.

Application filed January 5, 1900. Serial No. L30. (N mcdeld To (1.7]rub/mt 212: may concern:

lie it known that LCHARLEQ HENRY NOBLE, acitizen of the United States,residingat Ellis burg, in the county of Jefferson and State of New York,have invented certain new and useful improvements in Wrenches, of whichthe following is a full and complete specificaiiou, such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to wrenches; and the object. thereof is toprovide an improved tool of this class which is simple in adjustment andpositive in o 'icration.

My invention consists in the construction and arrangementof partshereinafter specifled.

in the drawings forming part of this specification, in which likereference characters denote like parts in the several views, Figure l isa longitudinal top view; Fig. 2, a longitudinal sectional view thereof,and Fig. 3a section of Fig. 2 on the line 3 thereof.

in the practice of my invention 1 provide a body port-ion comprising ashank at, carrying a fixed head 5 at one end and a handle 6 at theopposite end. The handle 6 is chambered longitudinally, as shown at 7 inFig. 2, and provided with a detachable bottom plate 8, secured theretoat 9 and by which said chamber is normally closed. A supplemental shank10 operates slidably within the chamber 7 in the handle 6 and carries atthe opposite end a supplemental fixed head 11, which operates inconnection with the head 5, which is fixed to the shank 1. The shank 4:is longitudinally bifurcated, as clearly shown in the drawings, and thesupplemental shank 10 operates slidably therein, carrying the head 11,and said head 11 is enlarged at one side of the shank t, as shown at 11and provided at the other side with two detachable side pieces 11",which are secured thereto when the parts are in the position shown inFigs. 1 and 3.

The operative faces of the side plates 11 and the portion of the head 11therebetween are serrated, as shown at 12 in Fig. 2, and thecorresponding operative surface of the head 5 is similarly serrated at13 in Fig. 2. The operative faces of the head 11 are coextensive inwidth and length with the operative faces of the head 5, the serratedfaces 12 and 13 being preferably formed outwardly diverging, and theoperative face 14 of the head 5 at the other side of the shank 4-,together with the operative face 15 of the enlarged portion 11 of thehead 11, are plane and parallelly arranged, as shown in Fig. 2.

The handle 6 is provided with a forwardlydirected ledge 16, whichextends between the sides of the bifurcated shank 4, and pivoted in saidshank, at either side thereof, at 17 is a catch 18, provided with acatch-head 1.9,which operates in connection with serrations 20, formedupon the upper surface of the supplemental shank 10. A spring 21 isinterposed between the ledge 16 and the inner end of the catch 18, whichis formed into a button 22, whereby said catch-head is normallymaintained in engagement with the serrations 20, and said serrations areso formed that said catch-head prevents the movement of the shank 1Orearwardly or into the chamber 7 in the handle 6, but allows the reversemovement thereof to bring the head 11 toward the head 5 or intoengagement therewith or with an object placed between said heads.

In assembling the parts of the Wrench above described the inner end ofthe shank 10 is inserted into the chamber 7 in the head 6, and the plate8 is then secured to said handle at 9. The side plates 11 are thenconnected with the portion of the head 11 which with the parts in theposition shown in the draw ings is included therebetween. The tool willthen be assembled for use, and the operation thereof will be manifestfrom the foregoing description when taken in connection with theaccompanying drawings.

When it is desired to Withdraw the head 11 from the head 5 to insert anobject between said heads, the button 22 is depressed against the spring21, raising the catch-head 19 from the serrations and allowing the innerend of the shank 10 to pass into the chamber 7. When the object to begripped has been adjnsted between said heads, the head 11 is forcedthereag'ainst, and the catch-head 19 prevents the retraction of saidhead 11, firmly gripping the object between said head and the head 5. Itis evident that the serrated divergent faces 12 and 13, as well as theplane parallel faces 15 and 14 of the respective heads 11 and 5, may beformed with any desired contour or relative arrangement and that theseveral other parts of my improved tool, as above described, may bevaried in construction and arrangement without de-' parting from thespirit of my invention or sacrificing the advantages thereof.

Having fully described my invention, I claim as new and desire to secureby Letters Patent 1. A wrench, comprising a handle provided with a shankhaving a stationary head or jaw at its outer end, said handle beingprovided with a longitudinal chamber, and a plate for closing the same,and said shank being longitudinally slotted, and a movable jaw or headprovided with a reduced portion which is passed through the slot in saidshank, and with a shank which moves in said slot and in the chamber inthe handle, the reduced portion of said movable jaw or head beingprovided with side pieces which form a part thereof, and a pivotedspring-operated catch mounted in the slot in the shank of the stationaryjaw or head, and provided with a thumb-piece adjacent to the handle, andwith a head which engages transverse teeth on the shank of the movablejaw or head, substantially as shown and described.

2. Awrench, comprising a handle provided with a shank having astationary head or jaw at its outer end, said handle being provided witha longitudinal chamber, and a plate for closing, the same, and saidshank being longitudinally slotted, and a movable jaw or headprovided'with a reduced portion which is passed through the slot in saidshank, and with a shank which moves in said slot and in the chamber inthe handle, the reduced portion of said movable jaw or head beingprovided with side pieces which form a part thereof, and a pivotedspring-operated catch mountedin the slot in the shank of the stationaryjaw, or head, and provided with a thumb-piece adjacent to the handle,and with a head which engages transverse teeth on the shank of themovable jaw or head, the transverse teeth and the head of the catchbeing so formed that the movable jaw is free to move in one direction,but cannot move in the other without the catch being operated,substantially as shown and described.

3. A wrench, comprising a handle provided with a shank having astationary head or jaw at its outer end, said shank being slottedlongitudinally, and said handle being provided with a longitudinalchamber which communicates with said slot, and a movable jaw or headprovided with a reduced portion which is passed through the slot in saidshank, and with a shank which moves in said slot and in the chamber inthe handle, the reduced portion of said movable jaw or head being pro-CHARLES HENRY NOBLE.
